Abstract

L'invention concerne un procédé de production de sable de fonderie, en particulier recyclé, à des fins de fonderie. Selon ce procédé, un mélange constitué d'une substance granulaire et d'agrégats, tel qu'un liant et de l'eau, est ajouté à une matière ne pouvant pas gonfler pas dans l'eau. Cette matière comporte des cavités présentant une surface spécifique supérieure à 10 m2/g, en particulier supérieure à 50 m2/g, de préférence supérieure à 100 m2/g, permettant d'améliorer les propriétés du sable de fonderie et/ou de réduire, de préférence, les émissions de substances polluantes et/ou odorantes.
